The Jedi being celibate monk's came from the rough draft screenplay from 1974. People don't have to like it but it was not created in 2000 or whenever Lucas started episode II.

Yeah its based on like a single throwaway line when Anakin Starkiller gets in trouble for having sex with some girl in a closet but its there.

In fact i don't have a hard time believing a lot of the prequel ideas came from already jettisoned stuff from those first prototype scripts.

The overly boring politics stuff. The stuff about a queen etc. The Kiber Crystal reminds me of midi clorians. Its a way to quantify the force. Kurtz suggested Lucas abandon it.
